Limitations

This figure measures density (per-capita supply), not access. Drive time, appointment availability, insurance acceptance, and wait times are not modeled here.
The CMS NPPES registry counts NPI-1 individual providers with the relevant taxonomy code. It does not capture PA-led or NP-led practices that operate under a different taxonomy.
NPPES does not publish a county-level field of practice in its public API. County- and ZIP-scoped queries surface state-level density, with the geographic context preserved on this page.
Population is the U.S. Census Bureau 2024 vintage estimate. Population shifts post-2024 are not yet reflected.
The "underserved" threshold is the parent study's transparent baseline cutoff; it is not a regulatory or clinical definition. See the parent study for the rationale.
